D-Link Air wireless products are based on industry standards to provide
easy-to-use and compatible high-speed wireless connectivity within your
home, business or public access wireless networks. D-Link wireless
products will allow you access to the data you want, when and where you
want it. You will be able to enjoy the freedom that wireless networking brings.
A WLAN (wireless local area network) is a cellular computer network that
transmits and receives data with radio signals instead of wires. WLANs are
used increasingly in both home and office environments, and public areas
such as airports, coffee shops and universities. Innovative ways to utilize
WLAN technology are helping people to work and communicate more
efficiently. Increased mobility and the absence of cabling and other fixed
infrastructure have proven to be beneficial for many users.
Wireless users can use the same applications they use on a wired network.
Wireless adapter cards used on laptop and desktop systems support the
same protocols as Ethernet adapter cards.
People use WLAN technology for many different purposes:
Mobility - Productivity increases when people have access to data in any
location within the operating range of the WLAN. Management decisions
based on real-time information can significantly improve worker efficiency.
Low Implementation Costs – WLANs are easy to set up, manage, change
and relocate. Networks that frequently change, both physically and logically,
can benefit from WLANs ease of implementation. WLANs can operate in
locations where installation of wiring may be impractical.
Installation and Network Expansion - Installing a WLAN system can be
fast and easy and can eliminate the need to pull cable through walls and
ceilings. Wireless technology allows the network to go where wires cannot –
even outside the home or office.
